Steel Defender Armor vests are specifically designed with two overriding objectives in mind: when you need to armor up quickly and you need the Level III protection of ballistic steel plating that will help protect you from blunt trauma, knife attacks and all the way up to high-velocity rifle bullets. Vests are MOLLE (Modular Lightweight Load-carrying Equipment) with plenty of PALS (Pouch Attachment Ladder System) for gear.
